bundle install is hanging when installing gems

I'm trying to install Canvas LMS on an Ubuntu 22.04 system.

I've tried running bundle install on the required gems as given by Canvas LMS.

This is the output I get:

Resolving dependencies...Fetching https://github.com/wrapbook/crystalball.gitFetching https://github.com/instructure/rspecq.gitFetching https://github.com/twitter/thrift_client.gitFetching https://github.com/kreynolds/cassandra-cql.gitFetching gem metadata from https://rubygems.org/........Resolving dependencies...Installing oj 3.16.3 with native extensionsInstalling pg_query 5.1.0 with native extensions

It gets stuck on install pg_query forever. I left it there for 2h and nothing happens.

Oddly, I did manage to install that gem manually by going gem install pg_query manually. It worked, and I can see the following when doing gem info pg_query

*** LOCAL GEMS ***pg_query (5.1.0)    Author: Lukas Fittl    Homepage: https://github.com/pganalyze/pg_query    License: BSD-3-Clause    Installed at: /home/ubuntu/.rbenv/versions/3.1.4/lib/ruby/gems/3.1.0    PostgreSQL query parsing and normalization library

I don't understand 2 things:

1. Why does it keep hanging when install pg_query?
2. Why does it even want to install pg_query? It's already there.
